r W Wk Georg EWDQv y INVENTOR ATTORNEY 4 Patented Dec. 31, 1929? I UNITED STATES PATENT OFFICE GEORGE DAVEY, OI LONG ISLAND CITY, NEW YORK V rtmnacr: warn I Application filed November 28, 1925. Serial No. 72,022.

My invention relates to furnace wall structure in which an inner .wall built up of a series of superimposed,'broken jointed blocks of high refractory materials is positioned and 5 held against a permanent masonry outer wall by a multiplicity of special bonding brick that are interlockable and integral with the inner wall and horizontally interlockably and movably held in vertical relation in the outer l0; wa,1l v

One of the objects of my invention is to construct a wall of interlocking high refractory furnace blocks inside of an outer wall, holding the inner wall from moving inwardlybut allowing the same to move vertically.

Another object of my invention is to construct a composite furnace wall consisting ofc an outer wall of masonry and an inner wall or lining of high refractory materials that will automatically adjust itself to the unequal expansion of the two walls dueto their differences of temperature and-simultaneously circulate air between the two walls to maintain that difference of temperature.

A still further object of my invention is to construct a' fixed outer wall of masonry, a vertically movable horizontally fixed inner wall of high refractory materials and maintain'a uniform air space between the said v twowalls. a

The air space referred to is provided for. by

each individual block having bosses on theinnerface thereof that act as stops for the blocks, when held by the bonding blocks against an outer masonry wall, these'bonding blocks positioned and fixed in the inner wall and interlocked in the outer wall that the segmental block or brick forming part of the unduly stressed while holding the inner wall wherein similar numerals refer to nKe parts throughout the several views, in which Figure-1, is an isometric view of a special brick or block forming part of the interlocking means integral with the outer wall.

Figure 7, is an isometric view of a special brick or block similar to Figure 5.

- Figure 8, is an isometric view of a segmental bonding brick or block similar to Figure 6. 7

Figure 9, is a section of a furnace wall showmg the relative positions of one form of the blocks and'the two walls.

Figure 10, is a plan on lines 10-10 of Figure 9.

Figure 1 1, is a section of a furnace wall sho the relative position of another form of bloc and the two walls, being of a similar character as shown in Figure 9.

'Fi re 12, is a plan taken on line 12-12 of Fig. 11 similar to that shown in Figure 10 except thatthis view'illustrates a segmens I tal wall.

Figure 13, is an elevation of Figure 9.

The block 1, shown in Figure 1, illustrating one half of the curved pocket or socket, which is made integral with the outer wall of the furnace, into which fits the block, hereinafter described as Figure 2,'is substantially rectangular in shape having a recessed part or curved socket portion 2 and a shouldered part 3, which when in parallelism with the part shown in Figure 2, forms a uniform expan sion s ace 4, illustrated in Figure 1, by the dotte lines and in the assembly Figure 9.

The interlocking bondin block or brick 5, shown in Figure 2, in its soc ets, one of which is shown in Figure 1, with two heads or curved portions 6 and 7, on each of its flat surfaces in proximity to one end, which fit into, cooperate with and are in parallelism to the sockets 2, shown in Figure 1, has adjacent to the opposite end a groove 8 on one side and a bead 9 on the other which interlock with gas tight unity into complementary parts in the unit blocks 10, forming the inner wall of said furnace.

These socket blocks 1, entirely within and integral with the outer wall 11, shown in Figure 9, have their inner faces 12, flush or in alignment with the inner face of said wall 11,

as is the face 16, of the block 5.

The bonding block 5, made rigid and integral withthe inner wall 13,having a face 16, in alignment with the face of the block 10, holds the inner wall from moving laterally by the beads or curved portions 6 and 7, which beads or curved portions fit into and cooperate with the sockets 2, in the blocks 1, but allow the 'wall 13, to move or expand vertically, said expansion being taken care of by the expansion space 4, formed upon the completion of the wall, as shown by Figure 9.

The bosses, feet or equivalent 14, integral with each block 10, forming stops for the said blocks, when held by the bonding blocks 5, against the inner wall 11, of the completed furnace wall also provide a uniform air space 15, between the inner wall 13, and the outer Wall 11, through whichspace air may be cir culated primarily to cool the inner wall 13, secondly to conserve the heat'thrown off by the furnace and thirdly to utilize this heat for a more complete combustion of the fuel within the combustion chamber of the furnace.

The socket block 19, shown in Figure 3, having a socket 2, is integral with the outer wall 11, and sets into said wall, projecting outwardly therefrom, from the point 17 which is equlvalent to the inner face of the outer wall 11. p

The bonding block 20, is of similar construction as is the blocks 5, except that it is shorter, the surface 16 on both blocks com]- prising the face of the inner wall 13.

The face 18, in Figure 2, is within the outer wall 11, while the-face 18 in ,Figure 4, is flush with the inner face of the outer wall 11.

In Figures 1, 2, 9 and 10, the bonding block 5, holding the wall 13, against the inner face of the outer wall 11, interlocks on both sides some distance from the wall 11.

In Fi ures 3, 4, and 11, the bonding block 20, holding the wall 13, against the inner face of the outer wall 11, interlocks on both sides be ond the inner face of the outer wall 11.

igure 5, illustrates a segmental socket block-27, having an inner curved face20, an

outer curved face 21, which is otherwise the cept it is utilized for building round walls for generators or the equivalent.

The bonding block 28, having an inner curved face 22, and an outer face 23, is of a similar character as is'the block shown in Figure 2, except that it is utilized in building round walls for generators or the equivaent. a

The segmental socket block 29, having a curved surface 26, is of a similar character as the blockshown in Figure 3, except that it is utilized in building round walls for generators or the equivalent.

The segmental bonding block 30, having curved surfaces 24 and 25, is of a similar character as the block shown in Figure 4, except that the same is utilized in building round walls for generators or the equivalent.

Having thus described and illustrated the preferred embodiment of my invention I do not desire to limit myself to the exact construction shown except so far as the same may be specifically claimed, since it is evident that modifications may be made without departing fromthe spirit of the invention or scope'of the claim.

I claim A furnace structure comprising a fixed outer wall, an inner lining wall of interlocking refractory blocks, and a plurality of sets of tie bricks holding the walls in fixed relation laterally but permitting-movement thereof 1n the general plane of the wall, each such set comprising a single brick fixedly secured in one wall and a pair of bricks fixedly secured in the other, the said pair of bricks being spaced from the single brick but mov ably interlocking therewith one at one face and the other, at the opposite face, to. provide freedom of relative movement between the walls in any direction in the general plane same in character as shown in Figure 1, ex-
